Kawaguchi Works1960

In 1957, predicting that Tokyo Works would soon be outgrown, a plot of land waspurchased in Aokicho, Kawaguchi, Saitama Prefecture earmarked to become a new
production site.
Commencing operations in February 1961, the new factory in Kawaguchi operated by
Tokyo Works was added to the production system and specialized in line production.
In its early days, Kawaguchi Works produced servo motors, automatic control devices
for hot-topping, hand crank generators for radio equipment, and power supplies used forsignal frequency meters. The following period saw a rise in production of various
products including magnetic tape units for computer peripherals, disk units, reel motors,
capstan motors, vacuum blowers, and sirocco fans.
It is during this period that the 1964 Tokyo Olympics were held, marking a major
turning point for Japan.
Leading up to the Showa 40s (1965-1974), when the electronics industry, notably
computers and semiconductors, would make great strides, SANYO DENKI madeproactive decisions to secure its foothold in the market.

Founded in 1927, 2019 marks SANYO DENKI’s 92nd year.
During this time, we have overcome several major economic fluctuations,and achieved steady growth through our original technologies and soundmanagement while recognizing the changing times.
In 1927, Japan had just seen the change of eras from Taisho to Showa, andthere were as yet no telephones or household appliances.
Later, after defeated in WW2, Japan rode a wave of high growth and,
together with the development of electronics technology, experienced dramaticchanges from lifestyle to business practices.
In the background of such lifestyle changes, new technological innovations
are always present.
The biggest change in recent years must be the information innovations
originating from the Internet.
The linking of computers resulted in the connection of people’s knowledge
and feelings all over the world. These information innovations led totechnologies such as IoT, AI (artificial intelligence), and autonomous driving,
and are now starting to change the world’s various existing systems. Integrated
with IoT and AI, robots today are expanding the range in which they canoperate at their own decisions. Right now, we are at the beginning of the next
paradigm shift.
SA N YO DEN K I suppor ts these changes f rom the perspective of
manufacturing (monozukuri in Japanese).
For example, lots of our Cooling Systems products are used to cool large
data processing cloud servers to facilitate stable operation. These products arealso used in non-cooling applications such as ventilation of highly-controlledplant factories and households.
Our Power Systems products support our information society by supplying
power to mission-critical equipment that cannot afford to be cut off, and servea major role in supporting lifelines in times of disaster.

SANYO DENKI Technical Report No.47 May 2019

Our Servo Systems products support high-speed and accurate movement ofrobots and machine tools.
In the future, in light of the declining birthrate and labor shortage, robots
will expand into medical and food markets too, widening the collaboration
with humans.

Technological innovations occur in a chain reaction, generating new
innovations one after another. A number of possibilities that humans could
only imagine in the past are becoming a reality today. Moving forward,
there is no doubt that AI will come up with solutions far beyond humancomprehension.
Even if the essence of human beings remains the same, technology can help
us unlock our potential. Who could have predicted our modern way of life inwhich things and people around the world can be easily connected? Just likepeople 92 years ago at the time of our company’s founding could not imagine
the world we live today, what the world will look like in 92 years from now will
be beyond our imagination for sure.
This year 2019 is a “year of change” where Japan said farewell to the Heisei
period and entered the Reiwa period. To date, SANYO DENKI has strived tostay ahead of the changing times and constantly developed new products as anindustry leader offering people happiness.
This issue of Technical Report provides a glimpse at some of our continuous
technological development in “Technical Developments in 2018,” including
IoT-enabled products and technologies that consider environmental durability
and people’s safety.
We at SANYO DENKI will view these changing times due to technologicalinnovations as opportunities to seize, and continue to “specialize in change.”Moreover, we will aim to become a top global brand by offering products andservices with value to our customers around the world in real time.

In recent years, due to the fullscale spread of IoT, ICT equipment
is required to offer larger capacity
and higher speed than ever before.
Particularly for next- generation
5G communication systems, how
to secure reliability and handle heatgeneration within equipment due
to high-speed, high-capacity dataprocessing and transmission areissues which need addressing.
Against such a backdrop, fansare now required to have higher

systems, and renewable energy inverters, an increasing
amount of heat is generated due to higher performanceand functionality of these devices. As such, high airflow,high static pressure centrifugal fans are used in a growing
number of cases.

Note:IP56 ingress protection rating
The degree of protection (IP code) is defined by
IEC (International Electrotechnical Commission)
60529 “DEGREES OF PROTECTION PROVIDED BY
ENCLOSURES (IP Code)” (IEC 60529:2001)

These devices are often used outdoors or in environments
where there is only AC power available, requiring ACdriven fans with waterproof performance. Another needis to lower fan power consumption for achieving energy
savings for devices.
As such, by using an AC-powered DC motor circuit in acentrifugal fan, we developed the San Ace 225AD Splash
Proof Centrifugal ACDC Fan which offers low power
consumption and waterproof performance.
I n parallel, we also developed the ø225 × 9 9 m m
Centrifugal ACDC Fan, a non-waterproof model with better
airflow vs. static pressure characteristics, for applications
that do not require waterproofing.
This article will introduce the performance and featuresof the new models as well as key points of development.

The new models are larger than our current models of
9AD type (92 × 92 mm, 120 × 120 mm). So, using the same
circuit configuration as these would result in insufficient
circuit capacity to operate the motor. To tackle this issue,
we focused on the following: choosing components which

1. Introduction
Recently, 1U servers and ICT equipment are processing
greater volumes of data. This results in greater heatgeneration that needs to be properly handled. Moreover, due
to higher functionality of the equipment itself, there is lessinternal space available for power supplies.
As such, fans mounted in such equipment need to be small

SANYO DENKI has developed the SANUPS A22A, amodular double conversion online UPS, to back up devices
requiring high reliability by using a parallel redundant
operation system, which, in combination with modular
5 kVA units, also makes it possible to perform maintenanceon individual UPS modules while supplying power to thedevices.
This article describes the overview and features of the
SANUPS A22A.

2. Product Overview
The SANUPS A22A was designed to provide backup
power for mission-critical devices used in data centers andpublic infrastructure facilities which require high reliability.
It consists of inverter modules, battery packs, and a cabinet.
Up to twenty-one 5 kVA inverter modules can be paralleledin the cabinet.
The lineup includes a 3-phase 4 -wire model with a

However, if this central control unit fails, the whole system
would stop. Even if the inverter module was very reliable,
if the reliability of the central control unit was low, thereliability of the whole system would be low.
Therefore, this product uses a fully autonomous control
method characterized by a control unit on each individual
inverter module instead of a central control unit for theparallel operation. Parallel operation is achieved by each
inverter module independently suppressing cross-currents.
As a result, by individually controlling each inverter moduleand eliminating the risk brought by the central control unit,
the reliability of the whole system is improved.

Servo Systems Division
Akio Miyahara

The applications and requirements
for servo systems are diversifying
in line with changes in industrial
structure and monozukuri, suchas globalization and the spread of
information and communicationt e c h n o l o g y. A g a i n s t s u c h ab a c kd r o p , t h e S e r v o Sy s t e m s
Division is working alongsidecustomers to develop new productsthat create new values.
This repor t will focus on new
products developed in FY 2018 suchas servo motors, servo amplifiers,
and controllers, and introduce thevarious features of each product toexplain how they create value forour customers.
First, we launched the
SANMOTION R1 series (flange size
40mm sq. to 80mm sq.), a smallcapacity, low-inertia AC servo motor
optimal for high hit rate applications.
This servo motor meets the needfor high acceleration/deceleration
driving and high-responsiveness,
and achieves higher torque androtation speed than our current
model. T his helps to shor ten
equipment cycle time and improve

productivity.
By adding this product to the
R series lineup, we have further
expanded our selection of motorsthat are suitable for the required
performance and characteristics.
Next, regarding servo amplifier
products, we have developed the
SANMOTION R 3E Model 400 VAC
input (15 0 A , 3 0 0 A ) for rated
outputs ranging from 5.5 to 30 kW
that can be used in regions with
400 VAC power sources, such as
Europe and Southeast Asia. The
depth of this servo amplifier has
been reduced while maintaining
mounting compatibility with ourcurrent model. When changing
from a 200 VAC input servo system,a transformer to conver t input
voltage is no longer required, whichhelps to make the system morecompact. We also enhanced themonitoring functions in order toconfirm the remaining componentl i fe of t h e h o l d i n g b r a ke s a n d

encoder communication. These
monitoring functions can contributeto s y s te m a t i c m a i nte n a n c e of

1. Introduction
The manufacturing industry is pushing ahead with thedevelopment of production equipment embedded withinformation and communication technology (ICT) to
respond faster to changing market conditions and demands.
ICT makes it possible to monitor production status in realtime, predict when equipment will require maintenance,and respond swiftly to potential issues—all which are vitalto maintaining high production standards. As such, motion
controllers require communication functions to gather andFig. 1 Appearance of the SMC100transmit data from production equipment to production
management systems. Moreover, to effectively utilize spaceon the production line and achieve high-mix low-volume
production, compact controllers, which can free up space incontrol panels, are in demand.
To meet such needs, we developed a compact motion
controller which features sequence, motion, and robot
control functions, as well as enhanced capabilities for

speed is reached. Here, we defined the time taken to reachthe commanded speed as “response time,” and changed load
inertia to calculate how response time would change.
For the simulation, we followed a simple calculation
flow using motion equations only, as shown in Figure 9.
We calculated the angular acceleration, α n , and angularvelocity, ωn, and carried out calculations repeatedly until thecommanded rotational angular velocity, ω1, was reached.
For torque Tn, the value of angular velocity ωn is obtained
from the torque vs. speed characteristics.

The new R1-Series can respond faster than the current
R2-Series even with a load inertia more than 10 times the
motor inertia. In this way, by exhibiting performance whichsets it apart from medium inertia motors, the advantageous
features of low inertia motors are more apparent.

4.2 Positioning of low inertia motor within
the R-Series
In this development, by adding the small-capacity
low inertia R1-Series to our current R-Series lineup, we
can propose the optimal motor to suit the customer’s
